The Toronto planning region includes the area within the municipal boundary of the City of Toronto. For the previous regional planning cycle that was completed in 2016, the Toronto Region was divided into two sub-regions - Central Toronto and Northern Toronto. The current regional planning cycle, initiated in late 2017, is not proposing the creation of any sub-regions within Toronto.

Regional planning activities in the Toronto Region

The regional planning cycle is underway for the Toronto Region, with an Integrated Regional Resource Plan (IRRP) anticipated to be posted in fall 2019.

A Scoping Assessment Outcome Report and Terms of Reference for the Toronto Region IRRP was finalized and posted in February 2018, following a two week comment period.

The IRRP is currently in development. An engagement initiative is available for interested parties to learn more about electricity planning activities undertaken for the Toronto region and offer input for consideration into the recommendations that will be outlined in the IRRP.

Toronto Region Working Group

A Working Group, consisting of the local distribution company in the region, Toronto Hydro-Electric System Limited, the local transmitter (Hydro One) and the IESO, are using the regional planning process to identify and meet local electricity needs.

Central Toronto sub-region

An Integrated Regional Resource Plan (IRRP) was released for the Central Toronto sub-region in April 2015.

An addendum to the Central Toronto sub-region was completed in February 2017. See the details.

Northern Toronto sub-region

A Needs Assessment for the Northern Toronto sub-region, the first step in the regional planning process, was completed in June, 2014. The study team determined that the needs identified for this sub-region can be addressed directly by the transmitter and local distribution companies, and that further regional coordination is not required. See the Needs Assessment report on Hydro One's website.
